Glad you were able to make it to the end, the Wheel affects the rotation based on how it spins, this is similar to how it works in real life but the main difference is a normal bike will have a free spinning wheel when the motor isnt engaged whereas with the motor on the wheel joints it slows to a stop when you dont accelerate. I did try disabling the motor when the W key is released but it caused a few other problems so its something ill find a solution for in the new game. Thanks for checking it out :)
